Rustom Jal Vakil: his contributions to cardiology.

Rustom Jal Vakil returned to India in 1938 after earning his medical degree from the University of London and focused on the treatment of heart ailments at a time when cardiology was not a distinct subspecialty in India. In 1949, after years of scrupulous collation and analysis of data, he published a watershed paper on the antihypertensive properties of Rauwolfia serpentina and effected a paradigm shift in the management of hypertension. Rauwolfia was the world's 1st successful blood-pressure-lowering agent, and its acceptance encouraged research scientists to pursue the development of other hypotensive drugs. Vakil was a prolific researcher whose contributions to Indian cardiovascular epidemiology--and to the whole of medical literature--were enormous. He was also a fine clinician with a remarkable gift for communication, be it with his patients, students, peers, or the lay public. All of this came together to make him the embodiment of a medically competent India.
